Application filed July 13, 1915. serial-No. 39,549.

To all wwmfit may concern:

Be it known that I, WILLIAM ERasrUs lVlLnrAMs, a citizen of the United States, and a= resident of Chicago, in the county of Cook and the State of Illinois, have invented a new and useful Improvement in- Pressed- Steel Journal-Boxes, as is set forth in the annexed specilication.

My invention relates to journal boxes: for railway carsand has for its object the manufacturel of journal boxes out of rolled sections of steel' and rolled plate whereby a very light,iyet very efficient and strong journal box ismade.

The invention isset forth in they claims In my journal box and'- the method-of making it, I provide first a straight rolled bar for the' topv of the boxmade of a peculiar section required for the design' of the box.` I then shear,.pun'ch, press and form thissection to make the top of the box. I then make what is known as the cellar of the journal box or oil holding. casing. out of a fiat sheet pressed up toform andy then apply additional necessary pieces to make the dust guardv and thelug. for the lid" When the parts are' suitably formed, they are assem bled and welded, rivet-ed or otherwise suitably connected to form the complete box.

Reference will be had to` the accompanying drawings.. in which' :y

Figi 23 is'- an end View' ofA the member shown ini Fig. 22.

Metal that may be rolled from large ingots is cheaper than cast metal 'as is-shown by the cost of rolled sections comparedl with steel castings or malleable ironi castings,l the materials out of which journal' boxes are now generally being made. invention is especially adapted for the use of rolled maing; which lies on the axle', and theV topof the journal box. The wedges and the br'asses` or journal bearings,` are made to interlock with onefanother as to strains endwiseandisidewise and the top'of the journal box is provided withy stops and shoulders adapted to hold the wedge and bearing in a definite position.

Generally speaking there are three contact points in the top of a journal box, the first' and most important is the flat bearing sur face upon which the weight of the load rests and then there are what are known as the back stops and the front stops which take up the end thrust of the journal bearing. These three surfaces must be relatively fixed and be of suitable form to meet the service requirements and the rest of the box need not be much more than an inclosure.

In the manufacture of my box,I first provide a rolled section las shown by the end View in Fig. 1, which is provided with two Iianges 2 on the top and one flange 3 on the bottom, with a thick portion l in the center a relatively thin section 5 for one edge-and a thin section 6 for the other edge.

This rolled section comes in long bars and the first operation is to cut it oli' to the right length as indicated by a plan view in Fig. 2. This is simply a shearing operation.

The next operation is to shear out the flange 3 at each end and in the middle portion of the sheet, leaving two small lugs 7 which form the front stops when the piece is finally formed.

The next operation is simply the cutting of two slots 80 in the rear end 5.v

The next operation is a pressing and bending operation and is usually done hot and it consists in bending the fiat section as indicated by 1 to the form shown in plan View 2 and end view 5. In this operation there are pushed down the two projections 8 at the ends of the plate and a lip or flange 9 is turned up at the back of the plate and a curved lip l0 is formed at the front of the plate.

' v The next operation consists in bending the ends of the plate down to the form shown in Figs. 6, 7, 8 and 9. rIhe projections 8 are then in vertical positions and form the shoulders for the back stops. rIhe front stops 7 are so positionedv on the plate that when the bending of the ends takes place to vertical position, the projections 7 abut into the angle of the bend, making a closure of the projections or front stops 7 with the vertical walls of the top piece after the latter is bent.

InsteadV of swaging or drawing the metal down to form the projections 8, I may roll two additional flanges 11, Figs. 10 vand 11 and cut them away as indicated by 12 in Fig. 11, leaving the central portion of the 1 plate smooth in the region where it comes in contact with the wedge on the inside of the box. Y

Instead of shearing out the flange 3 and the flanges 11 as last described to form the stops, I may when the metal is heated in the pressing operation above mentioned, push down these flanges to approximately the flat surface of the plate at the points where they are not needed, and thus save the shearing away of the flanges as described.

After the hot operations of swaging and bending have been performed as above indicated, the whole top is then submitted to a cold pressing operation which forms it to exact size. In this operation or at another operation, there are punched four holes 13 and two holes 14 through the top body of the top pieces (see Figs. 13, 15, 16 and 17). In this operation there is also performed a shearing operationA which trims out to sizey the notches 15 (see Fig. 15). The purpose of the holes and the notches is to permit the entrance of projections 23, 24, and 29 from the cellar which registers with the holes. Y

rIhe cellar is indicated by 16 and may be made in any suitable form desired, as relates to its general outline, and is here shown as being provided with a stiening boss or projection 17 on the bottom of the cellar which may serve for a seat for a jack screw head for jacking up the car truck. The back end of the cellar is formed with a stiffening rib 18 which also forms a recess in which to hold a flange 19 which forms the interior wall of the dust guard pocket indicated by 20.

The top portions of the sides ofthe cellar are olf set as indicated by 21, Fig. 18 so as to enter on the inside of the vertical walls of the top piece and yet have the side walls of the cellar just below the top piece the full width of the side wall of the top piece. Into the top of the side walls of the cellar there are embossed the two projections 22 which fit over the projections 8 of the top piece and thus form what are called the back stops of the journal box. Projections 23 and 2d of the sides of the cellar extend up` through the holes 13 and are bent over as is indicated by Figs. 12, 13 and 16, and thus securely lock the two sections of the journal box together.

Accurate registry of the middle portions of the cellar and top is secured by means of projections 25 formed on the cellar walls and entering corresponding holes 14k in the top member. A

Lips or Hang-es 26 are turned over on the remaining edges of the top sides of the cellar extending inward and forming as it were, stiffening ianges for the top edges of the cellar portion of the box and these flanges rest against the top of the inside of the journal box as is indicated by Figs. 16 and 17. V

At the rear of the box the top portions of the back end or back flanges of the cellar are bent outward or offset as is shown by 27 Figs. 12, 19 and 20 and a U-shaped connecting piece 28 embraces the offset portions 27 and forms a closure across the top at iso the back wall of the dust guard space or cavity 20.

At the rear of the cellar member and at thetop of the-projections 1-8 are projections 29 having shoulders 30 which fit against shoulders 31 ofthe fiange 9 as vshown in Figs. 13, 15, and these last mentioned projections fit snugly in the spaces 15, whereby .the cellar and top members are interlocked.

The flange 19 is provided with flanges 32 to fit vthe inside of the yrib 18 but these fianges do not extend across the bottom of the cellar but stop part way up the sides as is indicated by the dotted lines 33, Fig. 12. '.lhe main body of flange 19 is cut away at 34C at the ends just underneathl the top surface of the top piece, and thus forming a shoulder that projects under the back flange 9 of the top piece and holds the flange 19 down into position into the rib 18 of the box. Thus lthe inside wall of the dust guard cavity 20 is `automatically locked in place when the cellar and top are joined together.

The top, cellar, the flange 19 and the piece 28 are further fastened together by spot welds 35 as is indicated by Figi 12.

To the front end of the box I secure a lng 36 of any suitable form or construction which furnishes the pin hole for the journal box lid. This lug 36 may be spot welded, riveted or otherwise suitably secured to the top piece of the box.

My journal box as is here shown is designed to be used particularly with what is known as a side frame truck, wherein a steel casting or other suitable form of truck frame lits into the guide way across the top and down the sides of the journal box be tween the flanges 2 of the top `piece of the box. The guide ways of the side frame or truck member which rides on the journal box, normally extend below the bottom of the sides of the top piece and by making my cellar project out as I do, to the full width of the top piece below the top piece, the truck member then engages the sides of the cellar below the top piece so that in case of derailment or any unusual strain on the sides of the cellar, such strain is taken up also by the truck frame and the cellar is not required to sustain on its own account severe shocks and this permits a lighter construction of cellar than might otherwise be required.

The flanges 2 securely stiffen the whole box against strains which might produce diamond-shaped distortions and the projections 8 also serve in this stiii'ening feature.

It is essential to have a smooth flat surface on the top and inside of the box as is indicated by 38, Fig. 7 where the wedge comes in contact and hence I roll the bar 1 with a smooth flat surface on the inside. However, when the journal box is finished it is desirable to have some considerable clearance on the inside of the box on each side of the back stops or projections 8 and 22, hence in bending overfthe sides of the top plate as indicated by Figs. 2, 5, 6, `7, 8 and 9 I bend the thin sections on each side of the flanges 2 out tok the alinementV of the thicker portion 5, thus there occurs the rentrant curves and hence transmitted through the'box, are

directly applied on the thick portion 4f of the top piece, and since this is integrally united with the front and back stops as indicated, we have a very secure box notwithstanding that the rest of the top and the cellar may be made out of comparatively' lthin material.

My cellar extends as a continuous sheet entirely down the sides and across the bottom making no joints below the top of the inside, whereby leakage of oil at joints or rivets is prevented. The custom of the men who oil car journals is to pack waste securely in around on all sides that are open below the brass, and thus if there are any joints in a cellar below the top of the jonrnal box the oil is likely to leak out at the joints or at the rivet holes.

What I claim is:
